Rose not parsing continue inside If

I'm using `$ testFrontEnd ModTestCont.f90 -c `.

```fortran
Module ModTestCont

CONTAINS
Subroutine SRT2(FcLen)
integer, intent(in) :: FcLen

integer i

do i = 1, FcLen
p = p + 1
if(p > 12) continue
end do

End Subroutine SRT2
End Module ModTestCont
```
Output error:
```
testFrontEnd: Cxx_Grammar.C:17152: int Sg_File_Info::get_line() const: Assertion `this != __null' failed.
make: *** [exec_debug] Aborted (core dumped)
```
I'm using the following Rose version:
```
